AM and PM

Time is divided into hours, minutes, and seconds. Each day is 24 hours, each hour is 60 minutes, and each minute is 60 seconds. Example: 8:20 means 8 Hours and 20 Minutes. Time is displayed in two ways. The first is through a 24-hour clock, and the other is through an AM-PM clock. The abbreviation ‘AM’ stands for ante meridiem (before the garis bujur line has crossed the Sun or the time between midnight and 11.59 in the morning) PM stands for post-meridiem (after the garis bujur line has crossed the Sun or the time between noon and 11.59 at night).
